The cable 40 thus controls the: swiveling of the clipping mechanism aboutthe bearing post 47 andserves to keep the bed knife 4:5 always in proper contact with the hat surface also this same action of the cable 40 preventslthe clipping mechanism fromsudden tiltingiabout the post l7 at any point in itstraverse, for example, it prevents a sudden tilting of the clippingmechanism as it passes over the square of thehat. The vpivotal mounting of the clipping mechanism upon thepost 47,;in conjunction with the control thereof byvthe cable 40, thus insures that all portions ofithehat crown will be acted uponbythe rotating cutterand dependably clipped. j i i secured toltheclipperportion 46 as bymeans of a screw; 51 and slot 52. The projecting arm may thus beadj usted in position about u the axis of the post 4E7. By means of this ad:

justment the cable 40 may be madeto act upon? the clippervthrough an arm of force which tends to swing the clipper about the post d7. ln use, the bracket 49 is preferably sofadjusted that the cable 40 tends to tilt the clipperabout theposthl'? asthe clipping mechanismapproaches the band of the hat. and tends to tilt it so that 'theqportion of assuredthat the surface of the crown will be dependablyclipped all the way uptofthe brim. "The post 41 aroundwhich the cable I i 40 passes preferably provided with a roller which providesan anti-friction bearing forthe cable. The postal is formed upon a plate 54 which hasformed thereon also ears 55;in which pulley42 is carried, As shown in Figure 3, the plate 54 is secured to the arm 36 byzmeans of a bolt 5 6 passing through a generated about the axisof the arm 36. y The plateb lmay thusbe adjustedlto bringthe post llinto difiierent positions for adjusting clipping mechanism, u a a,

Turning againto Figures 1 and 2, mounted upon the clipper casing 46, by means of a suitable saddle 58, is a sma'll electric motor 59. 1 This motor thus moves with the clipper and is connected to drive the rotating cutter a 41 i asbymeans ofa belt passingovera pulmley fil on themotor] shaft and a pulley 62 i on the cutter shaft. The clipper casing 46 is l hollow, and "connected tothe rear side thereof As is seen in Figure 2 the bracket 49 to a which thecable lOvis attached: is adjustably they clipper nearest to the band drawn in} wardly withincreasingpressure. Thus it is slot 51? inthe plate,;the slot being arcuate and the directionof pull of the cablefilO upon the isya pipe63 for carrying awaythe clippings removedby thecutten Tothispipei63 is connected a flexible pipe of hose 6% which passes downwardly to a blower 65. The blower 65 is conveniently mounted upon a framework 66 extending between the cross members 13 of the frame and beneath the table orplatforni 11. The blower is driven from the driving motor 21 as by means of a belt 67 The blower 65 creates a strong suction drawing air inwardly about the co-act ingedges of the rotating cutter and its bed knife, downwardly through the flexible pipe 64-, and discharging through a pipe'68. This suction removes the clippings and at the same time assists in causing the fur fibres to stand up in position to be cut off by the clipper.

On the upper side of the clipper casin 46 i is mounted a nozzle 69 which is connected through a valve 70 with a hose71. The hose 71 is supplied with compressed air, as will be more fully described, and the nozzle 69 directs this compressed air in a streainagainst .thehat surface justin advance of the coactlng cutter and bed knife. As shown in"- Figure 8tlie nozzle 69 isof a width com inensuratewith that of the width of thebed knife and axial length of therotating cutter.

The streamof air directed at high pressure by the nozzle 69 against the hat surface loosdown, sothat they are placed in proper condition forefficient action thereon by the clipper, and the stream of air'also cleans the nap of any foreign material. a

ens the fur fibres which may be matted From the foregoing itwill be-seen that the clipping mechanism; :with its: driving motor 59, is caused to travel over the crown of the rotating'hat in a manner to dependably clip all portions ofthe crown; During the action of the clipping devicethenapof the hat is continually placed in proper condition for efficient actionbythe clipper and the clipof power occasionedthereby, is avoided. The

yielding pressure exertedby the cable 40in holdingthe clipping device against the hat insures continual proper engagementbetween thebed knife 45 and thehat surface, and also prevents anypossibility oftoo great pressure,

which might cause the bedfknife to dig into the hat andinjure thehat body. It willbe seenithat this clipping machine is one which is thoroughly practical and capable of producing a highgrade of workina rapid and i entirely-dependable manner.

i As has been mentionedabove, themachine may be adjusted so that the clipping de axis about which the arm 36 swings is adjustable lengthwise of the axis of rotation of the hat, and the hat support is also adjustments the hat and the axis of the arm i 36 may be Very conveniently brought into the proper relation for eflicient action of the a clipper upon hats of any depth of crown.

@ Turninghagain to the drivingimechanism of the machine, the shaft 25, upon which the worm wheel 24 ismounted, is supported in arm (Figures 3 and 4), and this arm 100 is pivoted upon; the frame 14 at 101 adjacent the rear thereofih The forward end of arm 100 is connected by a link'102 with a pin 103 which is eccentricallypositioned upon a shaft 104. a The shaft 104 extends. through the frame 14, having abearing therein," and has fixedluponits otherend a lever105. By turn ing the lever 105 the eccentric pin 103 is turned about theaxis ofthe shaft104so as to raise or lowerthe arm 100 and henceto raise or lower the worm wheel 24 which is lever 105 the worm wheel is moved into or y to start or stop the drive of the clipper :traversingmechanism. I Formed uponlever 105 is a projection106 whichengages a part i 14 of the frame to limit themovement of the leverin a direction to raise the wormwheel.

Referring now. to Figure 1, the lever l05 has ado-wnwardly projecting portion 105 .45, to which is connected a downwardly extend ing rod 107w The rod 107 is1connected at its j lower end 108 to a levejr109, forming part 3 0f avalve 110. The valve 110 *controls the machine and is connected vvith afisuitable source of compressed air by means of apipe @111. From the valvethe airis led through flexiblepipe or hose71 which passes toithe to start the drive of the worm wheel 24'and connections described, to start the flow of the wormj wheel is dropped out of engagesible to accommodate the machine to all of engage a groove 35. Thusthe position of the justableinthe same direction. By these ad supported'thereby. lThus by means of the out of engagement with the worm gear 23 flow of air through the pipe 71 to thenozzle pipe 112 and through a fitting-e113 to the j nozzle, Then the hand lever 105 is operated hence to start the traversing movement of the clipper, the valve 110 is openedby the air from the nozzle; against the hat. When ment withthe worm, thereby to interrupt/the.

conveniently toswing the. clipper to an inoperative position. i j i The clipper is held in this inoperative position by means of a pin 114 which iscarried movementof the clipper, theair i in a lug 115 onthe arm 39and the lower end of which ridesupon a-ledge 116 projecting outwardly from the arm 36, When'the arm 39is swung outwardly tocarry theclipper to its inoperative position, thepin 114 drops into an opening 117 to hold the arm and the clipper in such position. i j

Referring particularly to Figures 5 and 6, thereis pivoted upon a pin 118, projecting outwardly from the side of the arm 39, a link 119 having an arm120 which projects be: neath the head of thepin 114. The link'119 isconnected by a rod 121 with a thumb lever 122' pivoted upon the arm 39 by pin 123 and positioned adjacent to the handle 39% By depressing thethumb lever 122 the pin 114 is raised fromthe opening 117 to permitthe clipper to swing into; engagement with the hat under the urgeofithecable 40. With one hand the operator may thus grasp the handle 39 and depress the thumb lever 122,111 moving the clipper toward the hat. The other .1 hand of theoperator is thus free to guide orsteady the {clipper as it comes into contact with the hator for any other purpose. The

therapidly movingcutter blades if the drive r of the clipper were continuous while the operator'- placing a hat in position or removing a clipped hat. Still referring to Figures 5 and 6.; there is secured upon the end portion of arm36 a switch 124 which controls thecurrent'lto the clipper drivingmotor 59.

The wiring leadingbthrough the switch to themotor isjshown at 125in Figurel. The

switch isoperated bya button or plunger 126 which projects outwardlyrtoward the lug 115 ofthe arm 39:fThe button 126 is spring pressed-outwardly, and, when it is in its outer position,the circuit of the motor is closed, When the arm 39 is swung about its pivot 38 toymove the clipper away from thehat, the 1 lug 115 pressesthe button 126 inwardly and opens the switch to interruptthe drive of the motor 591 j The dropping of the pin114 into the opening in; the ledge 116 locks'the arm 39 in its outer positionyas has been described, and this also looks the button 126 in its inner position to break the circuit of the motor As soon as the clipper is moved toits operative position theswitch closes and the drive of the clipper is started.
